I was intrigued by Hiroaki Nishimura's work - and realised it would be very easy to create work in this style using rail sweeps in Rhino3D. So for the excercise I popped this together in under half an hour.

Dropped the file into the printer and left it over night - and now have a sweet new specimen vase. My wife, an accomplished ceramist, was disgusted at the ease at which a complete clod (a.k.a. me) could produce something so easily that would take her literally days to produce in porcelain. How the world changes...

If you want the highest resolution model, use the original Rhino .3DM file - the vase pictured was printed from a 140MB STL produced from the design files; a bit large for the average Thingiverse user...
